BOTTLE CLOSURE.

in the county of Kings and State of New York, have invented a new and Improved Bottle Closure, of which the following is a full, clear, and exact description.

This invention relates to bottle caps or 1 0 closures, and has for an object to provide an improved construction which is easily applied or removed without the use of tools. Another object in view is to provide a cap of the crimped type which may be applied by the hand and also removed by the hand.

A further object, more specifically, is to provide a cap or closure for bottles wherein part of the cap acts as sealing means and a second part as locking means.

In the accompanying drawings.'

Figure 1 is a side view of the upper part of a bottle, disclosing a cap embodying the invention applied thereto;

Fig. 2 is a view similar to Fig. l, but showing the cap immediately previous to its application; x

Fig. .3 is a sec-tionalview through Fig; 1 on the line 33;

Fig. 4 is-a perspective view of the sealing cap after the same has been removed.

Referring to the accompanying drawings by numeral, 1 indicates a bottle provided with a:neck 2 of any desired 'type and hav- 85 ing theusual bead 3 at the upper end whereby an annular depression or groove 4 is presented, which is adapted to receive the ordinary crimped cap-now commonly used.

In providing a cap for bottles containing soft drinks or any form of'etfervescent fluid, it is necessary to provide one Which.

willpresent an air-tight closure, and, at the same time, grip the bottle to such an extent as rto resist pressure fromv the contents of the bottle. The ,ordinary crimped cap now' :IlIl common use answers these requirements but necessitates the provision of a special form of capping mechanism, and also requires special meansfor removal. In the 50. present invention it is aimed to provide aclosure which will answer the same requirements.as the crimped cap heretofore used but will not necessitate the use of tools either in applying orremoving.

As shown in Figures 2, 3 and 4, the sealing cap 5 is substantially of the same form as the crimped cap now in common use, and includes a. cup-shaped imperforate section 6 in which a disk 7 of corkv or other suitable material is placed. Depending from the walls of the section 6' are a number of fingers 8," which are somewhatresilient by reason ofthe nature and shape of the metal, and these 'fingersare originally formed as shown in Figure 4 so as to flare.

When the sealing cap has been placed in position on the bottle as shown in Fig. 2, a locking cap 9 is slid thereover until it assumesthe position shown in Figs. 1 and 3. This willdepress the retaining fingers 8 so that they will automatically move into the groove 9, thereby presenting anchoring hook members. 1

Pressure. from within. the bottle cannot remove thecap 5 as this would necessitate straightening out the fingers 6, Which-will be substantially impossible when the cap 9 is in place. However, a person may readily pull the cap 9 off the cap 5, and then may with reasonableea'se pull the cap 9 off the bottle as the resiliency of the'fingers 8 will permit this action. i

in case it-should be desirable to use the cap 5 a second time, thecap 5may be readily placed in position on the bottle and the cap 9 reapplied, which will again seal the bottle.

It will be seen that both caps may be readily applied without the use of tools, and also may be'readily removed without the use of tools. The bead 10 on the cap 9 acts as a rigid bracing means for preventing spreading action of this cap as it bends the fingers 8 aswell as acting as stiffening means for maintaining the cap in proper condition' I claim: 7

1. A bottle closure comprising a' capformed of a plurality of retaining resilient.

curved fingers, a sealing disk arranged in and frictionally holding said fingers against movement on the neck of the bottle.

2. Abottle closure COIIIPI'ISIIIg' a sealing cap formed with. resilient curved means adapted to frictionally engagethe sides of.

the neck of a bottle, and a stifi locking cap I formed with an outwardly flaring edge adapted to slide over said sealing cap to force said means. against the 'neck of' the bottle. 1 1

3. A bottle closure comprising a sealing ing cap being formed with an outwardly flaring bead at its edge for preventing spreading of the cap adjacent its edge and 10 for engaging the curved portion of said fingers.
